    Notes: Summary The laminae near the optic tract which have previously been described as C, C1 and C2, have been studied electron microscopically and compared ] to the A laminae. In the A laminae most of the presumed retinogeniculate axons end in encapsulated synaptic zones that contain multiple interconnected synaptic profiles. Only a few of these axons form simple axodendritic synapses upon proximal dendritic segments of the largest cells. In the C laminae the situation is reversed. Most of the retinogeniculate axons end as simple synapses upon medium or small dendrites and few end in encapsulated synaptic zones. Further, these zones are simpler in the C laminae than in the A laminae. The neuronal profiles are smallest and the synaptic interconnections appear to be least complex in lamina C2, where there are only a few, small, presumed retinogeniculate terminals. Of the three C laminae, lamina C, furthest from the optic tract, shows the largest profiles and the most complex interconnections. Bundles of very fine axons occur in all the laminae, but they dominate the regions closest to the optic tract (lamina C2) where they tend to run parallel to the lamina. Some of the largest cells in laminae A, A1 and C are contacted by very fine perisomatic axons which contain round vesicles. These axons have not been described before and are likely to represent an input too fine to have been demonstrable by light microscopical methods.

    Desorption of Trichoderma reesei cellulase from cellulose by a range of desorbents (1989)

    Notes: The desorption of Trichoderma reesei cellulase from Avicel by a wide range of desorbents was measured. Emphasis was placed on desorption at alkaline pH. A maximum desorption of 65-68% Avicelase activity was achieved by contact with NaOH, pH 10.0, at 40°C for 5 min in the presence of 0.005% Triton X-100 or Tween 80. The design of a suitable desorption process using these conditions is discussed. Glycerol was also effective as a desorbent either alone or in combination with alkali and detergent. However, relatively high concentrations of glycerol were needed and the maximum desorption achieved, 68%, was not significantly greater than that with only alkali and detergent.

    A combined magnetic sector-time-of-flight mass spectrometer for structural determination studies by tandem mass spectrometry (1995)
    New York, NY : Wiley-Blackwell
    Rapid Communications in Mass Spectrometry 9 (1995), S. 1227-1233

    Notes: A combined magnetic sector-time-of-flight instrument has been constructed and used with both continuous (liquid secondary ion mass spectrometry and electrospray ionization) and pulsed (matrix-assisted laser desorption/ionization) ion sources. The design includes provision for both low- and high-energy gas collision induced decompositions and orthogonal acceleration of the product ions into the time-of-flight mass analyser. Tandem mass spectra may be acquired for singly and multiply charged precursor ions and reliable mass measurements are easily obtained. Product-ion mass spectra are quite reproducible regardless of any instability in the precursor ion beam intensity.
